I have a T5 retrofit and since installing the aquatic life hybrid fixture, the wires connecting the two bulb sockets are a few inches short of being able to mount on each side of the new fixture. I’d like to run two lower par bulbs for the two retrofit bulbs, but wanted to consult regarding how to extend the wires. I’m guessing this is nothing special? Just clip and solder new wires with shrink around it? What type of wire does they use (feels pretty stuff)? Thanks!
